HF Bond Multiple Subpanels
Bonding multiple subpanels creates a common low-impedance exit path for
the high frequency energy inside the cabinet. Subpanels that are not bonded
together do not necessarily share a common low-impedance path. This
difference in impedance can affect networks and other devices that span
multiple panels.
• Bond the top and bottom of each subpanel to the cabinet by using
25.4 mm (1.0 in.) by 6.35 mm (0.25 in.) wire braid. As a rule, the wider and
shorter the braid is, the better the bond.
• Scrape the paint from around each fastener to maximize metal-to-metal
contact.
